Description

A kind of novel railway locomotive car door

Technical field

The utility model belongs to railway locomotive equipment technology field, relates in particular to a kind of novel railway locomotive car door.

Background technology

At present, the railway locomotive technical development is swift and violent, require design strength, the appearance requirement of supporting equipment car door with it also more and more higher, traditional locomotive door board adopts the staking form, and door-plate generally flushes with door skeleton edge, yet this project organization can not well solve a frame welding distortion, the contraction Rear Door cooperates offset issue with skeleton, cause door not neat all around, the car door presentation quality is relatively poor, in addition, door-plate is connected by rivet with skeleton, and number of rivets is large, and car door intensity and appearance quality can not be guaranteed.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of novel railway locomotive car door, to improve car door intensity and presentation quality.

For achieving the above object, the utility model by the following technical solutions:

This novel railway locomotive car door of the present utility model, comprise door leaf, doorframe, door leaf is connected with doorframe by hinge, described door leaf comprises a skeleton, inner door panel, outside door-plate, door core, Men Xin is between inner door panel and outside door-plate, and door core and inner door panel are hot bonding by glued membrane respectively with outside door-plate is in the same place; The edge of outside door-plate is provided with bound edge, and the outer ledge position of door skeleton is provided with continuous outstanding overlap, and the bound edge turnover of described outside door-plate is on the overlap of described door skeleton; The position, inside edge of door skeleton is provided with continuous groove, and the edge of inner door panel is embedded in the groove of described door skeleton.

Further, a side corresponding with doorframe arranges step on the door skeleton, and step is provided with dovetail furrow, and stripper rubber is installed in the dovetail furrow; A side corresponding with the door skeleton on the doorframe arranges convex tendon, forms sealing when this convex tendon is squeezed in described stripper rubber.

Further, described step, dovetail furrow, stripper rubber and convex tendon include two covers that mutually stagger on the position.

Further, the bound edge of described outside door-plate is zig-zag in the fillet position of this outside door-plate.

The beneficial effects of the utility model are:

In the utility model, inner door panel is embedded in the skeleton groove, has guaranteed presentation quality around the car door inside edge.The bound edge of outside door-plate folds on the skeleton overlap, has guaranteed door outside edge presentation quality, has improved car door intensity.So this utility model intensity is high, good looking appearance.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, take a hint.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification sheets and the accompanying drawing.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

By reference to the accompanying drawings 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, the novel railway locomotive car door of the utility model embodiment is comprised of door leaf 1, doorframe 2, hinge 3; Door leaf 1, doorframe 2 connect by 3 hinges 3, and then realize the function of door leaf 1 switch.Described door leaf 1 is made of door skeleton 4, inner door panel 5, outside door-plate 6, aluminium honeycomb core 7, high strength glued membrane 8, outside stripper rubber 9, inner seal rubber 10.Aluminium honeycomb core 7 is filled in the skeleton 4, and inner door panel 5 is bonded in the groove 11 all around of a skeleton 4 by glued membrane 8, has guaranteed presentation quality around the car door inside edge; Outside door-plate 6 is bonded on the skeleton 4 by glued membrane 8 first, then by flanging machine the flanging 12 on the outside door-plate 6, flanging 13, flanging 14, flanging 15 and 4 sawtooth fillets 16 are distinguished on the overlap 17 of bound edges and door skeleton 4, guarantee presentation quality around the door outside edge, also improved the bulk strength of car door simultaneously.

With reference to the accompanying drawings 2, Fig. 3, Fig. 4, the utility model is installed outside stripper rubbers 9 by the dovetail furrow 19 of topping bar in 18 of door skeleton 4, the dovetail furrow 21 of getting out of a predicament or an embarrassing situation in 20 is installed inboard rubber 10.Convex tendon 22 on the doorframe 2, convex tendon 23 push respectively outside stripper rubber 9, inner seal rubber 10 seals, and are provided with two seals, favorable sealing property.

The invention structure of present embodiment has improved the presentation quality of traditional car door, has improved the bulk strength of car door.

Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
